75724 - duplicate data in stylesheets associated to XHTML documents !

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Daniel Glazman (:glazou) (not active in Mozilla any more)]

I discovered this bug writing CSS tests for the W3C CSS WG.

If an XHTML document contains two <style> elements, the first one containing
two rules a and b, and the second one a rule c, Mozilla will in fact
internally keep a first stylesheet made of a and b, and a second one made
of a b and c !!!!!

Demo with the test case attached in the viewer, select Dump Stylesheet in
Debug menu. If you don't trust the viewer, switch to a windows box with Document
Inspector compiled (/mozilla/extensions/inspector) : same result.
